Detailed Description

The present invention will be further described with reference to the following drawings and examples, which should not be construed as limiting the scope of the present invention.

The utility model relates to a wound orthopedics traction device, which is used for drawing the limbs or trunk of a patient so as to achieve the purpose of treatment and auxiliary treatment.

As shown in fig. 1-3, the orthopedic traction device for trauma of the present invention comprises a support plate 1. The supporting plate 1 is used for providing support for other parts of the traumatic orthopaedics traction device.

In the present invention, preferably, a plurality of support legs 13 are provided below the support plate 1. In this way, the support plate 1 is made to resemble a bed plate, facilitating the patient to place his or her site to be towed on it.

More preferably, a roller 14 is provided under each of the support legs 13. In this way, the movement of the traumatic orthopaedic distraction device is facilitated. For example, when traction treatment is required for a patient, the wound orthopedic traction device can be moved to a suitable location, such as a patient's ward, via the rollers 14 and aligned with the patient's bed, thereby facilitating traction treatment for the patient.

Still preferably, a locking mechanism is provided at each of the rollers 14. In this way, after moving the wound orthopedic traction device into position, the roller 14 can be locked by the locking mechanism so that it can no longer rotate, thereby fixing the wound orthopedic traction device, preventing movement during traction treatment, ensuring traction treatment effect, and preventing accidents from occurring.

As shown in fig. 2, the support plate 1 has a first slide groove 2 therein. Preferably, the first sliding chute 2 is arranged in the middle of the supporting plate 1, and the opening of the first sliding chute 2 is arranged upward.

As shown in fig. 1 and 3, the first chute 2 is provided therein with a slider 12 that can slide left and right therealong. One end of the supporting plate 1 is provided with a cylinder 3. The cylinder rod 4 of the cylinder 3 is arranged in the first runner 2 and is connected to the slide 12. Thus, under the driving of the cylinder 3, when the cylinder rod 4 of the cylinder 3 extends, the sliding block 12 can be driven to move left and right in the first sliding chute 2.

Wherein, a placing plate 5 is arranged on the slide block 12. The placing plate 5 is fixed with the slider 12 so that the placing plate 5 can move left and right along with the slider 12.

Two clamping plates 8 are arranged on the placing plate 5. Each clamping plate 8 is provided with a traction nail 9. The traction peg 9 is intended to be attached to a part of a patient requiring traction.

In the present invention, each of the traction nails 9 is provided with a force sensor. The traction force obtained by the traction nail 9 can be obtained through the force sensor, so that the traction force in the traction treatment process of the patient can be obtained.

Preferably, the placing plate 5 has a second chute 6 therein. A screw 7 is arranged in the second chute 6. The lead screw 7 is provided with two lead screw nuts which have opposite rotation directions and can move back and forth along the lead screw 7. The two clamping plates 8 are respectively arranged on the two screw nuts.

More preferably, a control nut 10 connected with the lead screw 7 and capable of controlling the lead screw 7 to rotate is further arranged on one side of the placing plate 5.

Because the turning directions of the two screw nuts are opposite, when the control nut 10 is screwed to drive the screw 7 to rotate, the rotation of the screw 7 drives the two screw nuts to move in opposite directions, so that the two clamping plates 8 are driven to move in opposite directions, and the parts needing to be pulled are tightened and loosened.

Furthermore, in the present invention, a controller 11 is further provided on the support plate 1. The solenoid valves of the cylinders 3 and each of the force sensors are connected to the controller 11. In this way, the controller 11 can determine whether the cylinder 3 continues to apply traction according to the sensing result of the force sensor, so that not only can the traction be automatically performed, but also the traction force and the traction process can be controlled, and a better traction effect can be obtained.

Preferably, the controller 11 has a steering screen. More preferably, the manipulation screen is a handwriting screen.

Thus, the medical staff can predetermine the traction force according to the condition of the patient and input the traction force through the handwriting screen. At this time, the controller 5 controls the cylinder 3 to apply traction force according to the input traction force, thereby realizing traction on the patient. And, the controller 11 may compare the sensing result of the force sensor with the traction force inputted, and determine whether the cylinder rod 3 of the cylinder 2 continues to apply traction force according to the comparison result. Therefore, accurate traction can be obtained, and a better traction effect is obtained.

When the wound orthopaedics traction device of the utility model is used for traction of a patient, the traction part of the patient, such as thigh, shank, arm, etc., is placed on the placing plate 5. Then, the control nut 10 is manually screwed to drive the two clamping plates 8 to move, so that the two clamping plates 8 are close to the traction part. Then, the traction nail 9 is manually screwed, and is connected with the traction part through the traction nail 9.

Then, the medical staff inputs traction force through the handwriting screen. Then, the controller 11 controls the cylinder 3 to move, and the traction is realized through the cylinder rod 4 of the cylinder 3. The force sensor senses tractive effort in real time during the towing process. When the traction force sensed by the force sensor is the same as the traction force input through the handwriting screen, the controller 11 controls the cylinder rod 4 of the cylinder 3 to be maintained still, and the traction part of the patient is dragged by using the traction force.

After the traction time is up, the controller 5 controls the cylinder rod 4 of the cylinder 3 to move reversely, the traction force is released, and the traction is finished.

The utility model discloses a wound orthopedics draw gear is equipped with force transducer in pulling the nail, can obtain traction force at any time, is convenient for master the condition of pulling to help obtaining better pulling down. In addition, the traction process is automatically carried out under the control of the controller without manual participation, and the accurate and controllable traction and treatment processes can be ensured. In addition, different traction forces can be set according to different parts, ages, recovery degrees and the like of patients, and traction is carried out by the set traction forces, so that good traction effect and treatment effect are achieved. Finally, the structure is convenient to adjust, can be suitable for various parts, such as different parts of thighs, shanks, upper arms, lower arms and the like, and can be suitable for different patients.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
